Description

Technical Field

[0001] The present invention belongs to the technical field of gibberellic acid extraction, and specifically relates to a continuous extraction device and extraction process for gibberellic acid. Background Art

[0002] Gibberellic acid is a kind of gibberellin and is a relatively widely used gibberellin compound at present. Gibberellic acid is a broad-spectrum plant growth regulator that can promote the growth and development of crops, enable them to mature earlier, increase yield, and improve quality; it can quickly break the dormancy of organs such as seeds, tubers, and bulbs, and promote germination; it can play the role of low-temperature vernalization and long-day lighting, promote and induce long-day vegetable crops to bloom in the current year, and increase the fruit setting rate or form seedless fruits.

[0003] In the prior art, in order to extract gibberellic acid, an ultrafiltration - nanofiltration process is usually used to filter and concentrate gibberellic acid. The specific process is as follows: The gibberellic acid fermentation broth enters the ultrafiltration system after pretreatment; the ultrafiltration membrane is based on mechanical sieving, utilizes the membrane pressure difference on both sides, and combines with the set molecular weight cut-off to effectively remove impurities such as suspended solids, organic macromolecules, bacteria, etc. in water, and the effective components enter the nanofiltration system along with the ultrafiltration product water; using the principle of selective permeation of the nanofiltration membrane, the target effective components are retained on the concentrated water side and separated from inorganic salts, and this step simultaneously realizes impurity removal and concentration. Higher-purity gibberellic acid can be obtained through subsequent treatment. However, during the ultrafiltration process, impurities will accumulate on the surface of the ultrafiltration membrane after the ultrafiltration membrane has been used for a period of time, resulting in a problem of decreased ultrafiltration effect of the fermentation broth. At the same time, the existing ultrafiltration devices cannot meet the ultrafiltration of the fermentation broth during regular maintenance and cleaning of the ultrafiltration membrane, making the continuous extraction process of the fermentation broth impossible.

[0004] Therefore, the present invention provides a continuous extraction device and extraction process for gibberellic acid. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A gibberellic acid continuous extraction device described in the present invention includes an outer tube body and a liquid inlet pipe. An inner tube body is arranged in the inner cavity of the outer tube body. An installation seat is fixed between the inner tube body and the outer tube body. An annular partition is fixedly connected to the center of the inner cavity of the inner tube body. One end of the liquid inlet pipe penetrates through the outer tube body and the annular partition and extends into the inner cavity of the inner tube body. The annular partition and the liquid inlet pipe divide the inner cavity of the inner tube body into a first cavity and a second cavity. A liquid spraying pipe one is fixedly connected to the liquid inlet pipe in the first cavity. A connecting seat one is fixedly connected between the liquid spraying pipe one and the annular partition. An elastic component one is arranged in the connecting seat one. The connecting seat one is slidably connected with a sealing part one through the elastic component one. The sealing part one is adapted to the inner cavity of the liquid spraying pipe one. A liquid spraying pipe two is fixedly connected to the liquid inlet pipe in the second cavity. A connecting seat two is fixedly connected between the liquid spraying pipe two and the annular partition. An elastic component two is arranged in the connecting seat two. The connecting seat two is slidably connected with a sealing part two through the elastic component two. The sealing part two is adapted to the inner cavity of the liquid spraying pipe two. Slots are arranged at the top and bottom of the annular partition. The two slots are respectively communicated with the inner cavities of the connecting seat one and the connecting seat two. Arc-shaped grooves are respectively opened at the top and bottom of the inner wall of the installation seat. A spring one is fixed in the arc-shaped groove. The other end of the spring one is fixedly connected with an arc-shaped valve flap. An electromagnetic component is fixed on the arc-shaped groove and the arc-shaped valve flap. A sealing plug is fixedly connected to the side of the arc-shaped valve flap away from the spring one. The sealing plug is slidably connected with the slot. One end of the sealing part one away from the liquid spraying pipe one penetrates through the annular partition and fits with the sealing plug. One end of the sealing part two away from the liquid spraying pipe two penetrates through the annular partition and fits with the sealing plug. A water inlet pipe is arranged in the inner cavity of the outer tube body. A water spraying component is evenly installed on the water inlet pipe. Liquid outlet pipes are fixedly connected to both sides of the bottom end of the outer tube body. Valves are installed on the liquid outlet pipes;The gibberellic acid fermentation liquid after preliminary filtration can enter the two sides of the inner tube body through the liquid inlet pipe from the liquid spray pipe one or the liquid spray pipe two. When it is necessary to flush the ultrafiltration membrane on the first cavity of the inner tube body, the electromagnetic component can be energized to drive the two arc-shaped valve flaps through the electromagnetic component. The upper arc-shaped valve flap drives the sealing plug-in to slide downward and squeeze the sealing component one, so that the sealing component one slides out to block the liquid spray pipe one, and the lower arc-shaped valve flap drives the sealing plug-in to slide upward and squeeze the sealing component two until it fits with the wedge-shaped groove, so that the sealing component two slides into the connecting seat two, and the blockage of the liquid spray pipe two is released. At this time, the fermentation liquid in the liquid inlet pipe can only be sprayed out from the liquid spray pipe two, and ultrafiltered through the ultrafiltration membrane on the second cavity of the inner tube body. At the same time, the water inlet pipe cooperates with the water spray component to flush the ultrafiltration membrane on the first cavity. When the first cavity is cleaned, After completion, the electromagnet is powered off, and the elastic force of spring 1 drives the two arc-shaped valve discs to slide back, so that the upper and lower sealing plug-ins are respectively away from seal 1 and seal 2. The elastic force of elastic component 1 can drive seal 1 to return to its original position, and the blockage of liquid spraying pipe 1 is released. The elastic force of elastic component 2 can drive seal 2 to return to its original position, and the blockage of liquid spraying pipe 2 is realized. At this time, the operation steps of flushing the first cavity are repeated to flush the ultrafiltration membrane on the second cavity. In this way, the ultrafiltration membranes on both sides of the inner tube body can be flushed in turn, ensuring uninterrupted and continuous ultrafiltration of gibberellin fermentation liquid, avoiding the situation that ultrafiltration cannot be performed during traditional regular maintenance and cleaning of ultrafiltration membranes, and at the same time, it can effectively avoid the accumulation of impurities on the surface of the ultrafiltration membrane, resulting in a decrease in the ultrafiltration effect of the fermentation liquid. ;

Detailed implementation manner

[0033] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the specific implementation manners.

[0034] Such as Figures 1-8As shown in the figure, a gibberellic acid continuous extraction device according to an embodiment of the present invention includes an outer tube body 1 and a liquid inlet pipe 2. An inner tube body 3 is provided in the inner cavity of the outer tube body 1. An installation seat 6 is fixed between the inner tube body 3 and the outer tube body 1. A circular partition 301 is fixedly connected to the center of the inner cavity of the inner tube body 3. One end of the liquid inlet pipe 2 penetrates through the outer tube body 1 and the circular partition 301 and extends into the inner cavity of the inner tube body 3. The circular partition 301 and the liquid inlet pipe 2 divide the inner cavity of the inner tube body 3 into a first cavity and a second cavity. A first liquid spraying pipe 13 is fixedly connected to the liquid inlet pipe 2 in the first cavity. A first connecting seat 16 is fixedly connected between the first liquid spraying pipe 13 and the circular partition 301. A first elastic component is provided in the first connecting seat 16. The first connecting seat 16 is slidably connected to a first sealing member 17 through the first elastic component. The first sealing member 17 is adapted to the inner cavity of the first liquid spraying pipe 13. A second liquid spraying pipe 14 is fixedly connected to the liquid inlet pipe 2 in the second cavity. A second connecting seat 21 is fixedly connected between the second liquid spraying pipe 14 and the circular partition 301. A second elastic component is provided in the second connecting seat 21. The second connecting seat 21 is slidably connected to a second sealing member 22 through the second elastic component. The second sealing member 22 is adapted to the inner cavity of the second liquid spraying pipe 14. Slots are provided at the top and bottom of the circular partition 301. The two slots are respectively communicated with the inner cavities of the first connecting seat 16 and the second connecting seat 21. Arc-shaped grooves 7 are provided at the top and bottom of the inner wall of the installation seat 6. A first spring 8 is fixed in the arc-shaped groove 7. The other end of the first spring 8 is fixedly connected to an arc-shaped valve flap 9. An electromagnetic component is fixed on the arc-shaped groove 7 and the arc-shaped valve flap 9. A sealing plug-in 20 is fixedly connected to the side of the arc-shaped valve flap 9 away from the first spring 8. The sealing plug-in 20 is slidably connected to the slot. One end of the first sealing member 17 away from the first liquid spraying pipe 13 penetrates through the circular partition 301 and fits with the sealing plug-in 20. One end of the second sealing member 22 away from the second liquid spraying pipe 14 penetrates through the circular partition 301 and fits with the sealing plug-in 20. A water inlet pipe 5 is provided in the inner cavity of the outer tube body 1. Spraying components 30 are uniformly installed on the water inlet pipe 5. Liquid outlet pipes 15 are fixedly connected to both sides of the bottom end of the outer tube body 1. Valves are installed on the liquid outlet pipes 15;During operation, the gibberellic acid fermentation broth after preliminary filtration can enter both sides of the inner tube body 3 through the liquid inlet pipe 2 by the first liquid spraying pipe 13 or the second liquid spraying pipe 14. When it is necessary to flush the ultrafiltration membrane on the first cavity of the inner tube body 3, the electromagnetic component can be powered on, and two arc-shaped valve flaps 9 are driven by the electromagnetic component. The upper arc-shaped valve flap 9 drives the sealing plug 20 to slide downward to squeeze the first seal 17, so that the first seal 17 slides out to block the first liquid spraying pipe 13. The lower arc-shaped valve flap 9 drives the sealing plug 20 to slide upward to squeeze the second seal 22 until it fits into the wedge-shaped groove, so that the second seal 22 slides into the second connecting seat 21, releasing the blockage of the second liquid spraying pipe 14. At this time, the fermentation broth in the liquid inlet pipe 2 can only be sprayed out from the second liquid spraying pipe 14 and undergoes ultrafiltration through the ultrafiltration membrane on the second cavity of the inner tube body 3. At the same time, the water inlet pipe 5 cooperates with the water spraying component 30 to flush the ultrafiltration membrane on the first cavity. When the cleaning of the first cavity is completed, the electromagnet 10 is powered off, and the two arc-shaped valve flaps 9 are driven to slide back by the elastic force of the first spring 8, so that the upper and lower sealing plugs 20 are respectively separated from the first seal 17 and the second seal 22. The first seal 17 can be driven to return to its original position by the elastic force of the first elastic component, releasing the blockage of the first liquid spraying pipe 13. The second seal 22 can be driven to return to its original position by the elastic force of the second elastic component, realizing the blockage of the second liquid spraying pipe 14. At this time, by repeating the operation steps when flushing the first cavity, the ultrafiltration membrane on the second cavity can be flushed. In this way, the ultrafiltration membranes on both sides of the inner tube body 3 can be alternately flushed, ensuring continuous ultrafiltration of the gibberellic acid fermentation broth without interruption, avoiding the situation where ultrafiltration cannot be carried out during traditional regular maintenance and cleaning of the ultrafiltration membrane, and effectively avoiding the accumulation of impurities on the surface of the ultrafiltration membrane, resulting in a decline in the ultrafiltration effect of the fermentation broth.

[0035] On both sides of the outer wall of the outer tube body 1, motors 25 are symmetrically installed. The motors 25 are fixedly connected to the first gears 26 through output shafts. The first gears 26 are meshed with the second gears 27. On both sides of the outer tube body 1, two water storage wheels 28 are symmetrically arranged. An annular water storage cavity 4 is arranged in the water storage wheels 28. The outer side end of the water inlet pipe 5 extends into the annular water storage cavity 4. An annular member one is rotatably connected to the water storage wheels 28. An annular member two is rotatably connected to the outer tube body 1. An annular member three is rotatably connected to the inner tube body 3. The annular member two is fixedly connected to the second gear 27. The water inlet pipe 5 is fixedly connected to the second gear 27, the annular member one and the annular member two. A cleaning component 29 is symmetrically arranged in the inner tube body 3. The cleaning component 29 is connected to the second gear 27, the annular member two and the annular member three. During operation, the output shaft is rotated by the motors 25, so that the first gears 26 drive the second gears 27 to rotate, and then the annular member two drives the annular member one, the annular member three, the water inlet pipe 5 and the rectangular pipe 2901 to rotate. The ultrafiltration membrane on the first cavity of the inner tube body 3 can be flushed by the rotating water spraying component 30 in cooperation with the cleaning component 29, strengthening the cleaning effect.

[0036] The water spraying assembly 30 includes a water spraying pipe 3001 and a conical nozzle 3002. The water spraying pipes 3001 are fixedly connected to the water inlet pipe 5 evenly. The water outlet end of the water spraying pipe 3001 is hinged with two conical nozzles 3002 through torsion springs. After the two conical nozzles 3002 are combined, they can form a seal for the water outlet end of the water spraying pipe 3001. A spiral groove is formed on the inner wall of the water spraying pipe 3001. During operation, the pressure of the water flow in the water inlet pipe 5 flushes open the conical nozzles 3002 on both sides of the water spraying pipe 3001 to perform backwashing on the ultrafiltration membrane on the first cavity of the inner tube body 3. Also, because the two flushing conical nozzles 3002 will expand to both sides to a certain extent, and in cooperation with the spiral groove provided on the inner wall of the water spraying pipe 3001, not only the flushing area is increased, but also the flushing intensity is enhanced, so that the ultrafiltration membrane can be better flushed. When the cleaning is completed, the water supply to the water storage wheel 28 is closed. At this time, the conical nozzles 3002 on both sides of the water spraying pipe 3001 are closed to form a seal for the water spraying pipe 3001, avoiding the entry of the fermentation broth during ultrafiltration.

[0037] The cleaning component 29 includes a rectangular pipe 2901, a top support 2902, a bracket 2904, and a sponge brush 2907. The rectangular pipe 2901 is fixedly connected to the second gear 27, the second annular member, and the third annular member. A top support 2902 is slidably connected inside the rectangular pipe 2901. The outer end of the top support 2902 is fixedly installed on the rectangular pipe 2901 through bolts. Branch pipes 2903 are evenly fixedly connected to the rectangular pipe 2901. A bracket 2904 is slidably connected inside the branch pipe 2903 through an elastic component three. One end of the bracket 2904 is fixedly connected to a conical member 2905. The conical member 2905 is in contact with the top support 2902. The two sides of the other end of the bracket 2904 are hinged to a support 2906 through torsion springs. A sponge brush 2907 is fixed on the support 2906. The two sides of the end of the branch pipe 2903 away from the rectangular pipe 2901 are hinged to two sealing plates 2908 through torsion springs. The two sealing plates 2908 can form a seal for the branch pipe 2903 when combined; during operation, before starting the motor 25, the staff first slides the top support 2902 into the rectangular pipe 2901 and then fixes it with bolts. When the top support 2902 slides into the rectangular pipe 2901, the top support 2902 will lift the conical member 2905, causing the bracket 2904 to lift the sealing plates 2908 on both sides of the branch pipe 2903 and slide out of the branch pipe 2903. At this time, the torsion springs at the connection between the bracket 2904 and the support 2906 will release the stored elastic force to drive the supports 2906 on both sides to unfold, making the sponge brush 2907 fit against the inner wall of the inner tube 3. When the motor 25 is started, the rotation of the rectangular pipe 2901 will drive the sponge brush 2907 to rotate together to clean the impurities attached to the inner wall of the inner tube 3. Coupled with the flushing component, the cleaning intensity of the ultrafiltration membrane is further enhanced, ensuring the ultrafiltration effect of the fermentation broth. When the cleaning of the first cavity is completed, turn off the motor 25 and remove the bolts, and slide the top support 2902 out of the rectangular pipe 2901. At this time, the top support 2902 is away from the conical member 2905, and the elastic force of the elastic component three drives the bracket 2904 to slide until the conical member 2905 fits against the inner wall of the rectangular pipe 2901. The supports 2906 on both sides of the bracket 2904 drive the sponge brush 2907 to be received into the branch pipe 2903. At the same time, the torsion spring force at the connection between the branch pipe 2903 and the sealing plate 2908 causes the sealing plate 2908 to close, forming a seal for the top of the branch pipe 2903 to prevent the fermentation broth from entering during ultrafiltration.

[0038] The first elastic component includes a first guiding block 18 and a second spring 19. At the top and bottom of the inner wall of the first connecting seat 16, there are first guiding grooves. A first guiding block 18 is slidably connected in the first guiding groove. The first guiding block 18 is fixedly connected to the first sealing member 17. A second spring 19 is fixed between the first guiding block 18 and the inner wall of the first guiding groove. One end of the first sealing member 17 away from the first liquid spraying pipe 13 is wedge-shaped and fits with the sealing plug-in 20. During operation, after the first cavity is cleaned, the electromagnet 10 is powered off. Driven by the elastic force of the stretched first spring 8, the arc-shaped valve flap 9 slides back, causing the sealing plug-in 20 to move away from the first sealing member 17. Driven by the elastic force of the compressed second spring 19, the first sealing member 17 can be driven to return to its original position, releasing the blockage of the first liquid spraying pipe 13, which is convenient for ultrafiltration of the first cavity.

[0039] The second elastic component includes a second guiding block 23 and a third spring 24. At the top and bottom of the inner wall of the second connecting seat 21, there are second guiding grooves. A second guiding block 23 is slidably connected in the second guiding groove. The second guiding block 23 is fixedly connected to the second sealing member 22. A third spring 24 is fixed between the second guiding block 23 and the inner wall of the second guiding groove. A wedge-shaped groove is provided at one end of the second sealing member 22 away from the second liquid spraying pipe 14, and the wedge-shaped groove fits with the sealing plug-in 20. During operation, after the first cavity is cleaned, the electromagnet 10 is powered off. Driven by the elastic force of the stretched first spring 8, the arc-shaped valve flap 9 slides back, causing the sealing plug-in 20 to move away from the second sealing member 22. Driven by the elastic force of the stretched third spring 24, the second sealing member 22 can be driven to return to its original position, achieving the blockage of the second liquid spraying pipe 14, which is convenient for cleaning of the second cavity.

[0040] The third elastic component includes a guiding rod 2909, a third guiding block 2910 and a fourth spring 2911. On both inner walls of the branch pipe 2903, there are third guiding grooves. A guiding rod 2909 is fixedly connected in the third guiding groove. A third guiding block 2910 is slidably connected to the guiding rod 2909. The third guiding block 2910 is fixedly connected to the side wall of the support 2904. A fourth spring 2911 is sleeved on the guiding rod 2909, and both ends of the fourth spring 2911 are fixedly connected to the third guiding block 2910 and the inner wall of the third guiding groove respectively. During operation, when the first cavity is cleaned, the motor 25 is turned off and the bolt is removed, and the top support member 2902 is slid out of the rectangular pipe 2901. At this time, the top support member 2902 moves away from the conical member 2905. The compressed fourth spring 2911 drives the support 2904 to slide through its elastic force until the conical member 2905 fits with the inner wall of the rectangular pipe 2901. The supports 2906 on both sides of the support 2904 drive the sponge brush 2907 to be received into the branch pipe 2903. At the same time, due to the torsional spring force at the connection between the branch pipe 2903 and the sealing plate 2908, the sealing plate 2908 is closed, forming a seal at the top of the branch pipe 2903 to prevent the fermentation broth from entering during ultrafiltration.

[0041] The inner end of the top support member 2902 is inclined, and the inclination angle is adapted to the conical member 2905. A water scraping groove is provided at the bottom of the inner end of the top support member 2902, and the water scraping groove is in a toothed shape. During operation, due to the design of the end of the top support member 2902, it is not only convenient to support the conical member 2905, but also convenient to scrape impurities and waste liquid in the rectangular pipe 2901 when sliding out of the top support member 2902.

[0042] The electromagnetic assembly includes an electromagnet 10 and a permanent magnet 12. The electromagnet 10 is embedded in the inner wall of the mounting seat 6, and the permanent magnet 12 is embedded in the arc-shaped valve flap 9. During operation, through the cooperation of the electromagnetic assembly, the first spring 8, the arc-shaped valve flap 9, the first seal 17 and the second seal 22, the ultrafiltration membranes on both sides of the inner pipe body 3 can be alternately flushed.

[0043] As Figure 9 shown, a gibberellic acid extraction process, which uses the above-mentioned continuous extraction device for gibberellic acid. This production process includes the following steps:

[0044] S1: Energize the electromagnetic assembly. Through the electromagnetic assembly, drive the two arc-shaped valve flaps 9 to squeeze the first seal 17 and the second seal 22, so that the first spray pipe 13 is blocked and the second spray pipe 14 is opened. The preliminarily filtered gibberellic acid fermentation broth enters one side of the inner pipe body 3 through the second spray pipe 14 through the inlet pipe 2 to achieve ultrafiltration.

[0045] S2: Start the motor 25. Through the cooperation of the motor 25, the first gear 26 and the second gear 27, drive the water inlet pipe 5 and the rectangular pipe 2901 to rotate. By connecting an external water supply source to the water storage wheel 28, the conical nozzle 3002 is opened, and the water flow flushes the ultrafiltration membrane. After sliding the top support member 2902 into the rectangular pipe 2901, fix it with bolts, so that the support 2906 and the sponge brush 2907 are opened to fit the inner wall of the inner pipe body 3 and rotate under the driving force of the motor 25 for cleaning.

[0046] S3: After the first cavity of the inner pipe body 3 is flushed, turn off the motor 25, close the water supply, disassemble the cleaning assembly 29 and cut off the power supply of the electromagnetic assembly in sequence, so that the first spray pipe 13 is opened and the second spray pipe 14 is blocked, and then perform a cleaning operation on the second cavity of the inner pipe body 3. Repeat this process to alternately flush the ultrafiltration membranes on both sides of the inner pipe body 3.

[0047] Working principle: The gibberellic acid fermentation broth after preliminary filtration can enter both sides of the inner tube body 3 through the liquid inlet pipe 2 by the liquid spraying pipe 13 or the liquid spraying pipe 14. When it is necessary to flush the ultrafiltration membrane on the first cavity of the inner tube body 3, the electromagnet 10 can be energized, so that the electromagnetic repulsion force between the electromagnet 10 and the permanent magnet 12 is generated, and then the upper and lower arc valve flaps 9 slide relatively. The upper arc valve flap 9 drives the sealing plug 20 to slide downward to squeeze the first sealing member 17, so that the first sealing member 17 slides out to block the liquid spraying pipe 13. The lower arc valve flap 9 drives the sealing plug 20 to slide upward to squeeze the second sealing member 22 until it fits into the wedge-shaped groove, so that the second sealing member 22 slides into the second connecting seat 21 to release the blockage of the liquid spraying pipe 14. At this time, the fermentation broth in the liquid inlet pipe 2 can only be sprayed out from the liquid spraying pipe 14 and pass through the ultrafiltration membrane on the second cavity of the inner tube body 3 for ultrafiltration. At the same time, the motor 25 on one side of the first cavity drives the output shaft to rotate, so that the first gear 26 drives the second gear 27 to rotate, and then the second annular member drives the first annular member, the third annular member, the water inlet pipe 5 and the rectangular pipe 2901 to rotate. The conical nozzles 3002 on both sides of the water spraying pipe 3001 are flushed open by the pressure of the water flow in the water inlet pipe 5 to perform backwashing on the ultrafiltration membrane on the first cavity of the inner tube body 3. And because the two conical nozzles 3002 after being flushed open will expand to both sides to a certain extent, and in cooperation with the spiral grooves provided on the inner wall of the water spraying pipe 3001, not only the flushing area is increased, but also the flushing strength is enhanced, so that the ultrafiltration membrane can be better flushed. Before starting the motor 25, the staff first slides the top support member 2902 into the rectangular pipe 2901 and then fixes it with bolts. When the top support member 2902 slides into the rectangular pipe 2901, the top support member 2902 will lift the conical member 2905, so that the bracket 2904 lifts the sealing plates 2908 on both sides of the branch pipe 2903 and slides out of the branch pipe 2903. At this time, the torsion spring at the connection between the bracket 2904 and the support 2906 will release the stored elastic force to drive the supports 2906 on both sides to expand, so that the sponge brush 2907 fits against the inner wall of the inner tube body 3. When the motor 25 is started, the rotation of the rectangular pipe 2901 will drive the sponge brush 2907 to rotate together to clean the impurities attached to the inner wall of the inner tube body 3. Coupled with the flushing assembly, the cleaning strength of the ultrafiltration membrane is further enhanced, ensuring the ultrafiltration effect of the fermentation broth. When the cleaning of the first cavity is completed, the motor 25 is turned off and the bolts are removed, and the top support member 2902 is slid out of the rectangular pipe 2901. At this time, the top support member 2902 is far away from the conical member 2905, and the compressed spring four 2911 drives the bracket 2904 to slide through the elastic force until the conical member 2905 fits against the inner wall of the rectangular pipe 2901. The supports 2906 on both sides of the bracket 2904 drive the sponge brush 2907 to be received into the branch pipe 2903. At the same time, the sealing plates 2908 are closed through the acting force of the torsion spring at the connection between the branch pipe 2903 and the sealing plates 2908 to form a seal at the top of the branch pipe 2903 to prevent the entry of the fermentation broth during ultrafiltration. When the cleaning is completed, the water supply to the water storage wheel 28 is turned off.At this time, the conical nozzles 3002 on both sides of the water spraying pipe 3001 are closed to form a seal for the water spraying pipe 3001, preventing the entry of the fermentation broth during ultrafiltration. After the cleaning assembly 29 is disassembled, the electromagnet 10 can be powered off. Under the elastic force of the stretched first spring 8, the two arc-shaped valve flaps 9 slide back, causing the upper and lower sealing plugs 20 to move away from the first seal 17 and the second seal 22 respectively. Under the elastic force of the compressed second spring 19, the first seal 17 can be driven to return to its original position, releasing the blockage of the first liquid spraying pipe 13. Under the elastic force of the stretched third spring 24, the second seal 22 can be driven to return to its original position to block the second liquid spraying pipe 14. At this time, by repeating the operation steps during the first cavity flushing, the ultrafiltration membrane on the second cavity can be flushed. By repeating this process, the ultrafiltration membranes on both sides of the inner pipe body 3 can be alternately flushed, ensuring continuous ultrafiltration of the gibberellin fermentation broth without interruption, avoiding the situation where ultrafiltration cannot be performed during traditional regular maintenance and cleaning of the ultrafiltration membrane. At the same time, it can effectively prevent the accumulation of impurities on the surface of the ultrafiltration membrane, which may cause a decline in the ultrafiltration effect of the fermentation broth.
